The chapter support is implemented using the IAMStreamSelect interface. Many popular players such as Media Player Classic provide a popup menu for this interface automatically so the chapter support should work naturally with them.

Thank you for updated plugins.Tags are displayed in Media Player Classic, but not in Winamp (v5.55, Nullsoft DirectShow Decoder v1.06).I suppose the problem is in WA plugin, have you checked it?I suppose I have to switch finally to foobar2000, but it needs time to get used to
